MASB Mudsill Anchor for CMU Block
On This Page
Product Details
The MASB is a mudsill anchor designed specifically to anchor a mudsill to concrete block foundations or walls. The unique design eliminates problems associated with misplaced anchor bolts. The MASB easily installs into wet concrete-grouted CMU block for a time-saving alternative to anchor bolts.
Key Features
- Offset design for use in concrete block applications
- One-piece design, so there are no nuts and washers to lose
- Unique design eliminates concerns about stud placement
Material
- 16 gauge
Finish
- Galvanized or ZMAX® coating; see Corrosion Information
Installation
- Use all specified fasteners; see General Notes.
- Fill CMU cell with concrete grout first, then place MASB into the grouted cell and adjust into position. Attach mudsill to anchor only after the concrete grout cures.
- CMU shall have a minimum f'm = 1,500 psi.
- The MASB mudsill anchors were tested in standard 8" CMU.

Load Tables
These products are available with additional corrosion protection.
- Loads have been increased for wind or earthquake loading, with no further increase allowed. Reduce where other loads govern.
- For uplift loads, provide attachment from mudsill to building's structural components to prevent cross-grain bending.
- For concrete stem wall applications, allowable loads are based on a minimum concrete stem wall width of 6".
- Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
Prescriptive Anchor Spacing
These products are available with additional corrosion protection.
- "Prescriptive" denotes designs per the IRC or conventional provisions of the IBC for wind speeds 140 mph or less, or for Seismic Design Category D and less (SDC E and less in IBC).
- Spacing is based on parallel-to-plate load direction only.
- Place anchors not more than 12" from the end of sill and splices per code.
- Grout-filled CMU (GFCMU) shall have a minimum compressive strength of f'm = 1,500 psi.
- Spacings apply to DF, SP, and HF sill plates.
